The invention discloses an automotive power-assisted steering electric controller with high assembly reliability, which comprises a PCB (printed circuit board), a base and a cover board, wherein a conical support column and a heat conducting seat in a right trapezoid shape are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns passing through the PCB, and is then fixed on the heat conducting seat by combining with screws; the cross sections of the two positioning columns are different; the base and the cover board are pressed together; the conical support column is positioned in the cover board and ensures that the cover board and the base are fastened tighter and tighter; the position, close to a left front corner, of the top of the cover board is provided with a circular anti-misloading mark; the back side of the base is provided with a plurality of strip-shaped heat conducting slots extending left and right. The automotive power-assisted steering electric controller effectively avoids the problem of slight shaking between the base and the cover board as well as between the PCB and the base after installation and effectively avoids the problem of overhigh local temperature of the PCB, prevents the cover board and the PCB from being installed oppositely, and has high assembly reliability.
